摘要： Disclosed subject matter is directed to techniques and systems for analyzing a system design having a phase array antenna. In at least one implementation, component models of individual components of the phased array antenna may be provided. The component models may be arranged as a multi-dimensional lookup table (LUT) in some embodiments. A single-channel model of antenna performance may be synthesized for the system design based on the component models. An analysis of the performance of the system design may then be performed using the single-channel model of antenna performance.

摘要： A coaxial-structure filter which utilizes a flat depression machined in the bottom surface of the filter cover as the resonant frequency determining element in a resonant cavity is disclosed. The depression is directly above the cavity resonator post when the cover is installed and provides a lumped capacitance from the post to the cover. The resonator post is machined flush with the resonator's top wall thereby placing the critical mechanical dimensions associated with the frequency determining elements in a more desirable location than prior methods (i.e., in the filter cover).
